The versatile forward suffered the injury in the fourth quarter of Sunday’s loss to the Oklahoma City Thunder when he went up to challenge a shot and came down on point guard Reggie Jackson’s foot.

“The first thing I did was grab my knee,” said Gibson, sporting a protective brace on the injured knee before the Bulls tipped off against Cleveland. “I went up for a regular shot-block and I came down so easily and it just gave way. I felt it right away. Right after the play, Thibs called timeout and he told me to go to the back.”

Gibson referred to the injury as a minor setback and given the early estimate of two weeks, he said he plans on pushing himself to return earlier, but also reminded himself that he has to follow doctor’s orders.

He was scheduled to undergo further observation to assure that there are no small tears in the ligament.

Although not as serious as Derrick Rose’s injury, Gibson has a new appreciation for what his teammate has gone through in suffering the injury and pushing through to return to the court.
